This is more of a note to people, but Ubuntu 10.10 (and therefore Mint 10) lost support on the 10th (of april). It won't get updates anymore, so it's probably time to move to Linux Mint 11 (which still has gnome 2), Linux Mint 12, Linux Mint 9 LTS (which also has gnome 2), LMDE, or something else.

Edit: Mint might support Mint 10 until the end of april (that's what it says on the download page). This is the first edition that's lost support since I've been using linux in general, so I'm not sure.

Correct. Ubuntu 10.10 is no longer supported since 10.10 is a "6-month release" version which is supported for 6 months. This means that every non-LTS version of Mint is also no longer supported. Only LTS versions will be supported for 3 years (desktop) and 5 years (server). Every other version will be supported for 6 months. This is the major flaw of Ubuntu / Mint, the quick succession of releases. As a result, too little time spent developing the product so well there are too many bugs in the final product. Would more time be devoted to developing the right product, then Ubuntu / Mint would be much stable and more reliable.

Yeah, Mint 10 was supported from October 10, 2010 to April 10 2010, which is eighteen months. Mint 9 LTS, Mint 11 , and Mint 12 are all still supported. Also, Ubuntu 12.04 LTS will be the first LTS that's supported for 5 years on the desktop as well as server.

Linux Mint 10 is no longer supported; any updates you get from the default repositories at Ubuntu or Linux Mint should cease this month. You may still receives updates from any repositories (PPAs for example) that you have added yourself. See above the link the to blog with announcement on this.
